GLASSlFLOWING AND SHEARING DEVICE. l

Application iled April 8, 192,1. Serial N o. 459,844.

To all whom t may concern:

Be it known that I, EDWARD MILLER, a citizen of the United States, and aresident of Columbus, county of Franklin, and State of Ohio, have invented a certain new and useful GlassvFlowing and Shearing Device; and I do hereby declare that the following is a full, clear, and exact ldescription thereof, reference being had to theaecompanying drawings, in which like numerals refer to like parts.

This invention relates to glass flowing and shearing devices.

The chief object of this invention is to provide means associated. with a lass discharging spout and a glass receiving mold such that a measured oi' predetermined amount of glass Will be dischargedfrom the spout into the mold to form an article of glassware.

The chief feature of 'this invention consists in associating with a continuous glass discharging spout and a glass receiving mold suitable shearing means for severing a predetermined amount of discharged glass from the remainder thereof,l and means for conveying the severed portion of the glass to the glass receiving mold.

Another feature of the invention consists in the details of construction and the operation o f the glass severing shears; and

another feature of the invention consists in the details of construction and the operation of the tiltable glass conveying means associated with the shearing means.

Still a further feature ofthe invention consists in actuating the shearing means and the conveying means in timed relation with each other.

The full nature of the invention will be' understood from the accompanying. drawvings and the following description and claims.

In the drawings, Fig. 1 is a side elevational view of the invention showing thev same associated 'with a glass'discharging lustrates the parts of' the linvention'in the glass receiving position whenv associated with the glass continuously discharging spout. Fig. 4 illustrates said-parts in the glass severing position. Fig. 5 illustrates the same parts with the severedportion of the glass after separation being received by the .conveying means.. Fig. 6 illustrates .retraction of the severing means so as to p ermit the invention to receive another portion 'of glass and also shows the' conveyin mea-ns discharging `the previously severe portion of glass into 'a suitable glass .receiving mold. i In the invention 10 indicates a suitable glass discharging spout, said -spout being provided with the glass discharging outlet or orifice 11. Beneath said spout and in juxtaposition thereto -is a suitable glass receiving mold 12 and interposed between said discharge orifice and said mold is 'suitable means for severing the continuously discharging glass into predetermined severed glass portions, and' associating therewith suitable glass conveying means for receiving the severed glass portion and then transporting the same, so that said severed glass portion will be discharged into the glass receivin mold. A

13 in icates a suitable support provided with the bracket portions 14: in parallel and spaced relation with each other.

Said' bracket portions are adapted to support asuitableearriage 15, said carriage being pro- 16. Said parallel brackets 14 and 16 cooperate with eachother and the hinge bolt or pin vided with correspondingbracket portions 17 to hingedly support the carriageupon'the supporting base or membei-.13 such that said carriage, upon which is supported the shearing means and the glass conveying means, may be moved from theA full line position vshown in Figs. 1 and 2 to the dotted line l osition shown in the last mentioned gu're.

4otatably supported by said carriage is a.

pair of shafts 18 and 19, said Vshafts in the present instance being in superposed relav tion. Suitably supported upon the framework (not shown) is another shaft 20and rotatable therewith is a drivin gear 21. Driven by said pinion 21 is a large gear 22 carried upon the shaft 18 Also carried upon said shaft and rotatable thereby' is a gear -23 whicliineshes with the gear 24 upon-the shaft 19. Thus power supplied by the lshaft 20V will be transmitted.

pinion or 1 sociated with the-gear- 23 isa pin member 25. The pin member 25 is eccentrically osimore fully -describ .i lo

.y tioned upon said with is an eccentric rod 26, which rod actua-tes the glass conve means, as will be hereinafter. 4 Upon the shaft 19, as shown clearly in Figs. 1 and 2, there is secured a cam' member 27, which cam `member is provided with an actuating tooth or cammin portion 28. Slidably supported in -the racket portions 29 and 30-which projectl transversely of the. bracket or plate portion 31 is a tappet 32. The tappet rod 32 is bifurcated at 33 and rotatably' supports a roller or cam follower 34. A spring member 35 has one end secured to the bracket portion 29 and the other end secured to a dnending hook 36V secured tothe tappet r Thus the Y spring 35 normally maintains the roller or lcarriage is rigidly secu-red, as by means ofcam llower 34 in contact with the cam member 27 such that said cam member is adapted to actuate the tappet rod when the proJection 28 engages the cam follower 34.

The free end of the tappet rod 32 is associated with the shearing mechanism to'operate the same. To the plate portion 31 of the the bolt 37, a stationary shearing blade 38 provided with the beveled edge 39. The stationary blade 38 is also provided with a curved ortion 40 such that the material severed wi l be moved so as to'be positioned in the curved portion 40 and retained therein during the severing operation. Pivotally supported at 41 upon the plate portion 31 is a movable shearing blade 42 provided with a beveled edge 43. Intermediate the free end of the movable shearing blade- 42 and the pivot support 41 is a screw bolt 44,

said bolt being secured to the free end of the cam actuated tap et rod, as shown clearly in F ig. 1. It will be remembered that the spring 35 maintains the shearing member 42 inthe non-shearing or open osition, as shown in Fig. 2, and the cam '27 positively closes said shears to sever the glass 'dis-` charged from the spout orifice.

.The bracket portion 30 is provided with a depending supporting portion 45. An L- shaped spoon member 46 is hingedly supported at 47 upon the depending supporting member 45. An ear 48 at the angle of said L portion'and depending therefrom is pivotally connected to the eccentric rod 26 such that in the movement of the eccentric vpin 25, said pin will cause the spoon member 46 to move from the full line position shown in Fi 1 to the dotted line position shown in said ligure. The spoon member 46 is provided with a suitable groove 49 to form a trough therein, and the head of said trough is closed by a curved portion 50 which cooperates with said trough in the elevated poar, and associated t eresition to forml a pocket into which the seveliled glass portion falls when severed by the s ears.

Since the shaft 20 and gears 21 and 22- actuate both mechanisms, it will be understood that said mechanismsoperate in timed relation with -each other. Figs. 3, 4, 5 and 6 illustrate the various steps in acomplete cycle of the invention. In Fig. 3 the shears as has heretofore .been described, are in the normal or open position such that the descending glass portion 51 passes through the same and is received by the cup portion of the L-shaped spoon. l Continued operation of the device causes the movable shearing member 42 to approach the stationary shearing member 38 and sever the same from the discharging glass, as shown in Figs. 4 and 5. During this operation the pivotally supported spoon is being tilted upon its pivot, and as illustrated in Fig. 6, said -spoon discharges'the severed glass portion 51a of the glass into the mold 12. At the same time the movable shearing member 42 has been retracted to the open position, so that the discharging glass will continue to pass through said shears and be received upon the spoon when the latter is moved after discharging the severed portion from the blank mold from the position shown in Fig. 1 to the position shown in Fig. 3.

While the invention has been described in considerable detail, many modifications thereof will readily suggest themselves to those skilled in the art, and it will be understood that these modifications are all considered to be within the broad purview of this invention.
